GRVY SOUTH prefixes in area code 530
NANPA records 5 assigned NXX blocks to rate center GRVY SOUTH in area code 530, 0.6% of the 782 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 5 holders hold those blocks, the largest being PACIFIC BELL (1), TELEPORT COMMUNICATIONS AMERICA, LLC - CA (1), COMMIO, LLC (1). The earliest assignment on record here is 2014-02-11 and the most recent 2023-08-10. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
